The predator stuff is good, but I've found this season with the leaves down on most all of our trees the Mossy Oak Treestand camo is ideal.

I don't worry too too much about my camo...I mainly try to get my stands in trees that have plenty of cover. Normally a single hemlock will suffice if it is in the right place. I also look for multilple trunked trees or trees that grow in a 3 or 4 trunk cluster. Setting a stand in a single trunked tree is, IMO, exposing too much of yourself and doesn't allow for normal movement without being spotted. The only time I ever had camo have an effect on my hunting was when I got some of the Predator Gray.....everything that walked by me saw me.....whether I moved or not. The Predator Brown has worked well as has most other camo patterns that are not too light in contrast to the surroundings, especially at dusk. I find it has been better for me to wear camo that is on the darker side rather than on the lighter side of the light spectrum.

I would say it sounds like you need to move maybe not much, could be 30 yards just depends.  Those deer come through their regularly after you are gone and they smell everything from where you walked in to where you climbed up the tree.  I have hunted many times in old worn out carheart bibs not 10 feet off the ground and have not been spotted.  I try to almost never hunt the same tree more than 2 timees a week and even that is probably to much.
